9 Claims. (01. 72-109) 7' v Theinvention relates to improvements in flange cagingwliich result in a continuous caging having transverse or cross. members (foranchoring the iirepr'ooflng material to the flange of the structural steel) spaced on any predetermined centers, but with the longitudinal. (connecting and sp acing) member locatedoutside of the line of flow of the plastic material around the edge and past the face of the flange, where it cannot induce voids or'imperfections inxthe thin fireproofing of the flange face, hereinafter called the soil-it areaf, and'as appears in Figure 1 this longitudinal member is itself outside the soflit area. with self-contained meansqof keeping the cross members, which anchorthfe sofit area fireproofing to the steel flange-fin the approximate center of the soffit fireproofing and with self-contained 7 means of adjustinga' standard length cross member to a plurality. of flange widths.

The transverse orcross member, a, is provided with ahook at one end to engageone edge of the flange, and a plurality ofprojeotions, which may be humps, 1), serving to keep'it away from the face of the flange regardless of the point at which the crossmemberis bent around the other edge of the flangethis bend being a field operation. Close contact with this last mentioned edge of the flange is avoided by'making the cross memher of a material so stiff that when the field bend is madeit will spring free from the edge of the structural steel and thus reenforce the concrete in the region outward from the flange edge. The

- factory-formed hook, c, is held the desired distance from the flange edge by stops or interferhumps on the transverse-:members during crating and uncrating. V p 5 In its broader aspects this invention is not lim- I itedto humps or projections on the transverse member, but for transverse members intended to -.va ntageous to have three or more humps. I

The term soflit area as used in this specificabe adapted to different, width flanges it is adtion means that portion of the concrete or other flreprooflng which, in a beam or girder, lies below the plane of the outer face of the bottom flange of the structural-metal member, and,in a column,

liesoutside ofthe plane of the outer face of either flange of the structural-metal member.

I claim:

, 1; Flange caging for structural metal members having longitudinal and transverse members, the

longitudinal member having means thereon to engage the edge of the flange, thereby providing a stop, and the transverse member having projections thereon to hold it away from the flange, 2. Flange caging for structural metal members having longitudinal and transverse members, the longitudinal member having means thereon to engage the edge of, the flangeand to cause the transverse member to project outward from the flange edge, thus providing a gap or space between'the caging and the edge of the flange and reenforcing the concrete in this region. 3. Flange caging for structural metal members having a longitudinal'member, a transverse member, and means on the longitudinal member to cause a portion of the caging to project outward beyond the flange edge-thus providing a gap or space between the caging and the edge of the flange and reenforcing the cencrete in this region. 4. Flange caging for structural metal members having longitudinal and transversemembers, a

longitudinal member being located outside and at the side of the sofiit area.

5, Flange caging for structural metal members having longitudinal and transverse members, the

transverse members being spaced away from the "flange edge to reenforce the concrete in this rely adaptedto nesting within small compass and parts, the projections consisting of humps and "the longitudinal members being located at the by the fact that a projection which engages the flange surface, cooperates with'the stifiness-of the material to cause the flange engaging ends of the member to spring free of the edge of the flange.

I 8. Flange caging for structural metal members having transverse members, means to hold them" away from the flange, anda longitudinal for spacing apart the transverse members, the longitudinal being located at the side of the soflit area so that the soflitarea is wholly unobstructed by it.

9. In a flange caging for structural metal members, thecombination of spacing and connecting members placed outsidethe sofiit area with cross members spaced away from the face of theflange by mechanical elements thereon and from the edge of the flange by the stiffness of the material thereof.
